God governs the world by the natural laws which he has established, and it would be impossible to define the extent to which he uses those laws to work out his providential purposes. It is probable that, in some cases, where he sees that a child of his needs discipline, or to be laid aside from worldly work and association so as to be drawn nearer to him, he may permit sickness to come upon him. In some passages sickness is threatened as a punishment. (See Deu. 28:27, 59, 60 and 61.) An instance is mentioned in Acts 12 33. On the other hand, it is certain that many diseases which afflict humanity are the result of disregard of sanitary laws, and although they may be used for the spiritual benefit of the sufferer, should not be attributed to God.
